Last Asylum: Plague Alliance Duel Strategy: How to Win Every Phase

The Alliance Duel is the biggest recurring event in Last Asylum: Plague. Six phases, each scoring a different kind of progress.

The alliances that win it are not always the ones that spend the most during the event. They are the ones that prepared the most before it started.

Most players play Alliance Duel on reaction. They spend as each phase opens and hope their resources hold out. Big accounts that know the phase structure do it differently. They save resources in the weeks before the event, set up their most expensive actions in advance, and use everything at the best-scoring moment of each phase.

This guide covers the Alliance Duel research order, the prep that separates top alliances from everyone else, and a phase-by-phase breakdown of where your time and resources actually score points.

Alliance Duel research: unlock it before the event

Alliance Duel research unlocks at Research Lab Level 15. If you are not at Lab Level 15 yet, this is the gate. Without it you get none of the event research bonuses.

Once it is open, follow a set order. Do not work through the tree at random.

1. Rush Super Rewards. This is the first node that really expands what the event pays out. Every Alliance Duel after this rewards you better.
2. Rush Arena Expert to level 20. Arena Expert is the best value in the Alliance Duel branch: at its max level 20 it gives up to +100% points. Do it right after Super Rewards and before the top reward tier.
3. Rush the tier 7-9 reward unlock. This is the top reward bracket. It raises the ceiling of what every future Alliance Duel pays out, which makes it one of the best research investments in the game. Skip it and the best rewards stay out of reach.
4. Max everything else. Work through the rest of the tree once the first three are done.

Why this order: reward tier unlocks pay out in every Alliance Duel you play from then on. Unlocking tier 7-9 early does not help one event. It helps every event after it.

Alliance Duel rewards preparation, not reaction

The most important Alliance Duel idea for big accounts: saving resources between events is how you get the most rewards for the least extra spend.

Each of the six phases scores one category. Building upgrades score in the Territory phase, research completions in the Tech phase, hero upgrades in the Hero Growth phase. If you wait for each phase to open before you gather what you need, you pay full cost on a short timeline.

If you have been saving since the last Alliance Duel ended, those resources came in over a full cycle. Each point costs you less, and you never scramble to top up mid-event.

Falcon Quests show this best. Each Falcon Quest gives 10,000 points when used. Players who save them through the week before Alliance Duel and use them at the start of each phase score a lot more than players who use them as they get them. Same quests. Timing is the whole difference.

Alliance Duel phase by phase

Phase 1: Enhance Raven

The first phase scores Raven activity: Raven Essence, Raven Fruit, rallies, Raven Survival Battle and squad activity.

What to do:

• Use saved Falcon Quests at the start of the phase for fast points
• Use all the Raven Essence and Raven Fruit you saved since the last event
• Send gathering squads outside your Sanctuary to farm RSS, since the activity scores points
• Join Raven Survival Battle for extra points
• Run rally attacks with alliance members

What to save: your building speedups. Territory Development comes next, and that is where construction scores.

Phase 2: Territory Development

This phase scores building upgrades and construction. It also gives you the most room to prepare, through the pre-build strategy.

The pre-build strategy: if a building takes more than one day, start it before Phase 2 opens but do not tap the completion hammer. Let it finish while the phase is not active, then claim it when Phase 2 starts. Points count when you tap the hammer, not when the build finishes. It is one of the most reliable edges in the whole event, and it costs nothing extra. Only timing.

What to do:

• Use saved building speedups on Sanctuary upgrades and building requirements
• Recruit survivors where it gives building or territory points
• Claim any pre-built completions by tapping their hammers at the start of the phase
• Keep Falcon Quests for Phase 3

What to save: do not tap builds that finish after Phase 2 ends. Hold them for Phase 5 (War Preparation), which also scores construction.

Phase 3: Tech Research

Phase 3 scores research completions. Same logic as Phase 2: queue research that takes more than one day before the phase opens, so it finishes inside the Phase 3 scoring window.

What to do:

• Start any research of 1 day or more before Phase 3 opens, timed to finish during Phase 3
• Open all your saved Raven gear chests on this day, since gear activity counts toward tech scoring
• Use science speedups if your research queue needs a push
• Use saved Falcon Quests at the start of the phase
• Use RSS to score points, but stop once you hit the point maximum for that resource type

What to save: training speedups. Troop training scores in Phase 5, not here.

Phase 4: Hero Growth

Phase 4 scores hero investment: star upgrades, hero levels, skill upgrades and hero recruitment.

What to do:

• Upgrade hero stars on your main squad (Arthur, Marlena and your core roster)
• Level heroes and upgrade skills with saved EXP boxes
• Use the Universal Shards (UR, SSR, SR) you saved since the last event
• Open saved Recruit Tickets to add heroes and score recruitment points
• Join Hero Survival Battle for extra points

What to save: training speedups for Phase 5. Keep some EXP if you want to score in Hero Survival Battle instead of spending it all here.

The idea: use hero resources you have been saving for weeks, not packs bought during the phase. A resource scores the same no matter when you got it. Preparation decides how much you have to use.

Phase 5: War Preparation

Phase 5 scores troop training, construction and preparation.

What to do:

• Use saved Falcon Quests
• Use the troop training speedups you saved since Phase 1. Wait for the Troops Training Survival Battle window if you can, since joining it multiplies your score
• Use your remaining building and research speedups
• Claim the build completions you held over from Phase 2

Timing note: if your troop training takes several days, start it before Phase 5 opens so it finishes in the scoring window. Same pre-build logic as Phases 2 and 3.

Phase 6: Raid Enemy

The last phase is PvP. Points come from attacking enemies, defending, garrisoning alliance members and joining rallies.

If your account is built for attack: hit enemy bases, join rallies and push territory objectives. This is where your combat investment from the whole cycle pays off.

If you are not ready to attack or want to protect your troops: shield before the phase opens. You can still score by garrisoning or defending alliance members under attack, but only if you are sure your power is higher than the attacker. A failed defense costs troops and scores nothing.

Phase 6 is for players who built toward it. Phases 1 to 5 decide whether you can fight when it opens.

Alliance leader playbook

Share the phase calendar before the event starts. Members who know Phase 2 scores building and Phase 3 scores research save the right resources for the right phase. Members who do not will burn building speedups in Phase 3 and have nothing left for Phase 2.

Enforce pre-build discipline. The most common Alliance Duel mistake in competitive alliances is members tapping finished builds right away instead of holding them for the right phase. Say it clearly before every event.

Line up Falcon Quest timing. Each Falcon Quest gives 10,000 points. An alliance where everyone saves them and uses them at phase starts scores far more than one where members use them through the week. Set the save window together.

Make sure every member has Alliance Duel research unlocked. Members below Lab Level 15, or without the tier 7-9 reward node, score below what they could. Find them and put research on your pre-event checklist.

Set clear Phase 6 roles. Members with low troop counts should shield and help on defense. Members with strong combat accounts should be organised into attacks before the phase opens, not improvised during it.

How big accounts play Alliance Duel

Alliance Duel punishes reactive spending and rewards preparation. Every phase has a resource type that scores points. Resources saved before the event score at full value with no extra spend. Resources bought during the event under phase pressure cost more and score the same.

For accounts already buying packs every month, the question is not whether to play Alliance Duel fully. It is whether your pack timing lines up with the event cycle, so your resources are stocked and ready when each phase opens instead of bought in a rush after it starts.

Quick summary

• Alliance Duel research unlocks at Lab Level 15. Order: Super Rewards, Arena Expert to level 20, tier 7-9 rewards, then everything else.
• Saving resources between events is the core strategy. Same resources, more points, less extra spend per phase.
• Falcon Quests give 10,000 points each. Save them through the week and use them at the start of each phase.
• Pre-build: start long builds and research before each phase opens, and do not tap the hammer until the right scoring phase is live.
• Phase 3 (Tech Research): open all saved Raven gear chests that day, and start 1-day+ research before the phase so it finishes inside the window.
• Phase 6 (Raid Enemy): shield if you are not ready to attack. Garrison and defend only if your power is higher than the attacker.
• Top up before the event, not during it. Resources bought before a phase opens score the same as resources saved over weeks.
